4 4
5 13 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
6 sandbox.h, sandbox_futils.c:
7 Modify get_sandbox_pids_file(), get_sandbox_log() and get_sandbox_debug_log()
8 to use TMPDIR if present in environment.
9
10 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
11 Remove sandbox_log_file from main() as its no longer used.
12
13 13 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
14 sandbox_futils.c:
15 Add get_sandbox_debug_log(), and use it (add behaviour similar to SANDBOX_LOG
16 if already exported when sandbox started). Fix get_sandbox_log() and new
17 get_sandbox_debug_log() to not use already exported environment variables if
18 they have '/' in them. Use snprintf()'s instead of strncpy()'s. More
19 SB_PATH_MAX fixes.
20
21* sandbox-1.2.7 (2005/05/12)
22
23 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
24 sandbox_futils.c:
25 More path limit fixes. Declare SB_BUF_LEN global and use it where needed.
26
27 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
28 Fix paths limited to 255 chars. Fix get_sandbox_dir() returning a string
29 with '(null)' in it if we did not call sandbox with absolute path.
30
31 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
32 Set SANDBOX_ON *before* doing the child's env stuff, else its not set
33 for the child.
34
35 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
36 Remove global preload_adaptable as it is no longer used.
37
38 12 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
39 Rewrite environment stuff to only be set when execve'ing the child process
40 to try and avoid issues like bug #91541 that causes sandbox to crash if
41 we set LD_PRELOAD sandbox side already.
42
43 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
44 Move print_sandbox_log() up to make things neater.
45
46 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
47 Remove load_preload_libs(), as its not used anymore.
48
49 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
50 Remove NO_FORK stuff, as its not used, and 'strace -f' works just fine.
51
52 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
53 Remove USE_SYSTEM_SHELL stuff, as it is not secure, and not in use.
54
55 11 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h:
56 Remove ld.so.preload crap - we are not going to use it again.
57
58 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox_futils.c:
59 Fix typo in code that checks if we got valid group information, causing a
60 segmentation fault, bug #91637.
61
62* sandbox-1.2.6 (2005/05/10)
63
64 10 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
65 Do not use LD_PRELOAD if it contains libtsocks.so, as it breaks sandbox
66 for some odd reason, bug #91541.
67
68 09 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
69 Fix typo (sizeof -> strlen).
70
71 08 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
72 rewrote the sbcontext caching code so it accounts for env changes since lib
73 initialization.
74
75 05 May 2005; Martin Schlemmer <azarah@gentoo.org> configure.in, libctest.c:
76 We create libctest.c via configure, so no need to keep it around. Do some
77 cleanup related to libctest.c and libctest during configure.
78
79 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
80 Add rename support of symlinks pointing to protected files/directories.
81
82* sandbox-1.2.5 (2005/05/04)
83
84 04 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c,
85 sandbox.bashrc:
86 Do not reset already set LD_PRELOAD when starting sandbox. If LD_PRELOAD is
87 already set, init of the env vars fails for some reason, so do this later on,
88 and do not warn (bug #91431).
89
90 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c, sandbox.h,
91 sandbox.bashrc:
92 Fixup sandbox and sandbox.bashrc to call bash with the proper .bashrc.
93
94* sandbox-1.2.4 (2005/05/03)
95
96 03 May 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
97 Do not init the env entries with each call, as it creates too many calls to
98 lstat, etc. Should speedup things a bit, bug #91040.
99
100 03 May 2005; Martin Schlemmer <azarah@gentoo.org> sandbox.c:
101 Add /dev/pty to default write list. Noticed by Morfic.
102
103 02 May 2005; Mike Frysinger <vapier@gentoo.org> configure.in, localdecls.h,
104 sandbox.h:
105 uClibc doesn't support dlvsym() so add a configure check to make sure it doesn't
106 exist. Also update localdecls.h so BROKEN_RTLD_NEXT isn't defined in uClibc.
107
108* sandbox-1.2.3 (2005/04/29)
109
110 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> configure.in:
111 Do not check for (*&#$(* CXX or F77.
112
113 29 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
114 Do not append '/' to pathname in filter_path() if it already ends with it.
115
116 28 Apr 2005; Mike Frysinger <vapier@gentoo.org> Makefile.am, configure.in:
117 With az's help, clean up autotools to work with cross-compiling.
118
119* sandbox-1.2.2 (2005/04/28)
120
121 28 Apr 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
122 Only check for /dev/{null,zero} for unlink hack, else ricers using /dev/shm
123 have issues; bug #90592.
124
125* sandbox-1.2.1 (2005/04/23)
126
127 23 Apr 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
128 getcwd.c, libsandbox.c, localdecls.h, sandbox.h, sandbox_futils.c:
129 Make sure all functions used in libsandbox.c is declared static. Define
130 SB_STATIC in localdecls.h for this. Include sandbox_futils.c rather than
131 linking with its object. Hopefully this will fix bug #90153.
132
133* sandbox-1.2 (2005/04/23)
134
135 22 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
136 Allow lchown a symlink in write-allowed path pointing to write-denied
137 target.
138
139 21 Mar 2005; Marius Mauch <genone@gentoo.org> libsandbox.c:
140 Also show resolved symlink names in the log.
141
142 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, libsandbox.c:
143 Seems -nostdlib was the problem with the constructor/destructor - remove it
144 from Makefile.am, and change the constructor/destructor names again.
145
146 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
147 Also rename the _init() and _fini() declarations.
148
149 14 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c, sandbox.c:
150 Fixup the constructor/destructor function names again (they should be _init()
151 and _fini() it seems, and not being called caused sandbox_lib_path to be
152 unset, and thus breaking the execve() wrapper's LD_PRELOAD protection).
153 Add both the path in given SANDBOX_x variable, as well as its symlink
154 resolved path in init_env_entries(). Modify filter_path() to be able to
155 resolve paths without resolving symlinks, as well as to be able to resolve
156 symlinks. Fix a possible segfault in check_access(). Add symlink resolving
157 to check_access() resolving bug #31019. Add 'hack' for unlink, as the fix
158 for bug #31019 cause access violations if we try to remove a symlink that is
159 not in protected path, but points to a protected path. Fix a memory leak in
160 sandbox.c (sandbox_pids_file in main()). Fix the realpath() calls in main()
161 (sandbox.c) being unchecked. Fix the debug logname not having the pid in it
162 (pid_string was uninitialized). General syntax cleanups.
163
164 09 Mar 2005; Brian Harring <ferringb@gentoo.org> sandbox.c: Fixed the
165 infamous "pids file is not a regular file" w/out newline bug.
166
167 09 Mar 2005; Brian Harring <ferringb@gentoo.org> Makefile.am, configure.in:
168 Correct libc_version path detection, since it was screwing up if libdir !=
169 "/lib/".
170
171 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> libsandbox.c:
172 Hack to make sure sandboxed process cannot remove a device node, bug #79836.
173
174 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am:
175 Fix symbols.in not added to dist.
176
177 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
178 getcwd.c, libsandbox.c, sandbox.c, sandbox.h, sandbox_futils.c:
179 White space fixes.
180
181 02 Mar 2005; Martin Schlemmer <azarah@gentoo.org> Makefile.am, canonicalize.c,
182 configure.in, getcwd.c, libsandbox.c, symbols.in:
183 Fix inverse test logic in canonicalize.c, use a strncpy. Fix gcc warning in
184 getcwd.c. Add symbols.in and logic to Makefile.am to generate symbol versions
185 for glibc and other libc's that use this. Update libsandbox.c to use these
186 symbol versions if available. Fix exec wrapper to re-export LD_PRELOAD if the
187 process unset it.
188
5 01 May 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c: 189 01 Mar 2005; Brian Harring <ferringb@gentoo.org> libsandbox.c:
6 killed off _init and _fini in favor of 190 killed off _init and _fini in favor of
7 void __attribute__ ((constructor)) init_func and 191 void __attribute__ ((constructor)) init_func and
8 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated. 192 void __attribute__ ((destructor)) closing_func. _(init|func) were deprecated.
9 193
10 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c, 194 06 Dec 2004; Brian Harring <ferringb@gentoo.org> Makefile.am, libsandbox.c,
